Dave, The FCC position is a bit different to Europe region 1. LW was never used for broadcasting in the US. LW came into very early radio use here, due to Marconi's successful Trans Atlantic 'spark' transmissions around 160 kHz LW. Daventry was a very early successful LW broadcasting station set up by Marconi on 1500 metres. LW 1500 'National' transferred to Droitwich in 1934. It gave truly 'National' coverage from 1 TX, with MW following for BBC 'regional' broadcasting. That was around the time when MW's began use in the USA for the 'regional states'. LW never 'began' there. There is some YouTube stuff on USA LW 'hobby activity at frequencies below 190 kHz down to around 160 kHz, David
